Caution, Warning or Notice Labels varied from state to state but all said basically the same thing...that the taxes have been paid for this box of cigars and you are not allowed to refill this box with more cigars after the original content has been sold or 'we will get you'. OK, OK that isn't the correct legalese but you get the point. There are some very nice litho's on Caution labels and every collection should have at least a couple.
